The enzyme was cloned, expressed and purified internally in an e.coli (e.coli) expression vector using classical methods. mu.L of DMSO or inhibitor dilutions in DMSO and 80. mu.L of enzyme in buffer A were added to each well of a clear polystyrene plate (Corning, 3628). The plate was immediately read in a microplate spectrophotometer (BioTek, PowerWave HT) at 485nm for background subtraction. After pre-incubation at room temperature for 30 min, 15 μ L of NCF (final concentration 200 μ M) was finally added to each well. The final enzyme concentrations were 0.1nM (TEM-1), 0.075nM (SHV-1), 0.4nM (CTX-M-15), 1nM (KPC-2), 0.2nM (P99AmpC), 0.2nM (CMY-37), 0.4nM (AmpC Pseudomonas aeruginosa (P. aeruginosa)), 0.2nM (OXA-1), 1.2nM (OXA-11), 0.4nM (OXA-15) and 0.3nM (OXA-48). After incubation at room temperature for 20 minutes, the plates were read again at 485 nm. Enzyme activity was obtained by subtracting the background from the final signal and conversion to enzyme inhibition was done using uninhibited wells. IC conversion Using XLFIT (IDBS)50Curve fitting is a classical langmuir equilibrium model of the Slope (Hill Slope).
